### What problem does this PR solve?
Issue Number: N/A
Related PR: N/A
Problem Summary:
Add an external Iceberg regression case for duplicate position delete files
that both reference the same data file position. The test builds a legal
Iceberg v2 merge-on-read Parquet table through the external Spark/Iceberg
environment, appends two position-delete files for position 0 with a Java
fixture, then forces the legacy file scanner with
`enable_file_scanner_v2=false` before running `DELETE WHERE true`.
A fixed build should delete the remaining visible rows without crashing and
leave the table empty. The case also checks the default FileScannerV2 path
before the legacy scanner step to confirm the fixture is readable and logically
contains rows `20, 30, 40`.
